Title: Forward error correction at mpeg-2 transport stream layer
Inventor: WAN XIANG
IPC: H04N19/89
Filed: 1999-12-13
Abstract: The invention is for a system and method for performing forward error correction on an MPEG-2 transport stream that has optional error correction information embedded within the transport stream. An error correction operation is performed on a super group of packets within the transport stream. The error correction data is inserted into a created trailer group of MPEG-2 compliant transport stream packets having no payload, but only an adaptation field The trailer group packets are optional and therefore can be discarded by a standard MPEG-2 decoder, but can also be used to recover data lost in the transmission of the transport stream. The invention results in a system and method to correct an MPEG-2 transport stream that can be used in any one of the digital video broadcast (DVB) formats, without the need for error correction decoders which are specific to the DVB format.

Title: Process for improving the corrosion resistance of a metal surface
Inventor: HONDA TAKUMI
IPC: C09D201/06
Filed: 1999-01-13
Abstract: A resin coating is formed on a metal surface using an aqueous autodepositing resin composition that contains oxidizing agent, acid, and carboxyl-functional and/or hydroxyl-functional water-dispersible or water-soluble resin and, optionally, metal ions; the resulting coating, while still in its uncured condition, is subjected to post-treatment with an aqueous solution containing from 0.5 to 5.0 g/L of amine and from 10 to 100 g/L (solids) of water-soluble amino resin molecules that bear at least two alkoxymethylamino, methylolamino, and/or imino groups; and the coating is then dried and cured. This provides a highly anticorrosive coating on the metal, and contrary to an analogous process in which the post-treatment solution contains amino resin but not amine, the post-treatment solution remains stable and provides continuing high quality coating performance even after a considerable amount of metal surface per unit volume of post-treatment solution has been processed.

Title: Data distribution network and high pass bridging filter or combiner therefor
Inventor: JEFFERY ROSS A
IPC: H04M1/738
Filed: 2000-10-26
Abstract: A filter bridge, coupler or combiner coupling dedicated subscriber telephone lines at specified frequencies turns a local network of telephone wires into a connectionless network at the specified frequencies while maintaining a circuit-switched network of dedicated subscriber telephone lines at all other frequencies. Telephone carriers remain isolated to each dedicated subscriber telephone line, while other telecommunications service (e.g. audio/video) carriers can be distributed over the same local twisted pair network as a connectionless network within a specified range of frequencies. Any range of frequencies can be specified for the connectionless network, for example using a high pass filter or a notch filter. In the case where the redistributor dynamically allocates frequencies for the redistributed signals, a dynamic filter bridge may be used to select a passband corresponding to a frequency allocated by the redistributor for redistributed signals at any particular time.
